Stewart has failed to break through with a regular role in the big leagues despite bouncing around a few organizations in recent seasons. The Pirates were the latest team to take a chance on him, as he was claimed off waivers in November after the Red Sox designated him for assignment. Ultimately, his chances of contributing in Pittsburgh are better than they were in Boston, but he's failed to miss bats when called upon to this point. If he's unable to impress as a starter in spring training, Stewart will likely try to salvage his career by making a move into the bullpen.

2012

Stewart made his MLB debut in June for the Blue Jays, but they sent him to the White Sox as part of the Edwin Jackson/Colby Rasmus trade after three starts. He served as the Sox's sixth starter after the deal, and he largely stunk. He did throw a one-hitter against a hapless Twins squad, but he posted a 7.56 ERA and 26:13 K:BB in his other nine appearances. His groundball tendencies should play well at U.S. Cellular Field, but he will need to exhibit a better control of the strike zone to stick in the majors. He could compete for a back-of-the-rotation gig out of spring training, but chances are he begins 2012 at Triple-A Charlotte.

2011

Stewart's overall numbers at Double-A New Hampshire last season weren't great, but he improved greatly as the season wore on after a sluggish start. He'll spend most of the year at Triple-A Las Vegas and could get a look if injuries dictate. Stewart is only 24 and has ascended through the Jays' system quickly after being a third-round pick in 2008. He's worth considering in keeper formats given his dominance at lower levels prior to last season.

2010

Stewart came over to Toronto in the Scott Rolen trade in a season that saw him pitch at four different stops along the way, ultimately ending up in Triple-A Las Vegas. He struggled at times for both the Reds and Jays at Triple-A (1.675 WHIP) despite a 2.10 ERA and it remains to be seen if the Jays view him as a starter or reliever down the road. His career minor league numbers are nice (1.70 ERA, 1.283 WHIP, 8.4 K/9IP in 138 IP) but he'll need to handle the jump to Triple-A more effectively before we get too excited.
